So, I did a software as my final project in order to get my degree in audio Technics. I would Like to get the copyright of this soft so I can sell it or give it away for free or whatever without had the risk of somebody gets credit for what I did.

Did you guys know what to do in order to get the copyright of a software?

Generally copyright is automatic on creation as posted above, and the only issue is being able to prove that you created it. A good start would be not to give out your source code and then to register your work.

You might get better advice if you tell us where you are from, because IP laws are different all over the world. There's no point someone telling you what to do in the US only for you to find out that the US copyright office isn't interested in dealing with someone from Burundi.

The same applies to patents - the EPO excludes computer programs from being patentable, for example.

Most countries have agreements that honour copyright of other countries, but I have no idea how Peru fits in with this. Again, you probably want to ask a local IP lawyer. Peru is a bit "exotic", I've no idea how many Peruvians there are on KVR and I'd doubt that a high percentage of them know the intricacies of IP law.

Edit: here's a PDF from the US copuright office about treaties and other countries. It's obviously US-centric but Peru is listed and might give you something to start with:

You can probably research yourself which countries have signed what treaties etc. Though I'd still recommend getting professional advice before spending the $200.

Scenario 1: someone has the same idea as you (doesn't even need to "borrow" it from you, although not ruled out), builds his own implementation, is very succesful at marketing it, sells it at a lower price with better support, so is getting your customers.

Scenario 2: you build a good implementation of your idea and publish it. Some lowlife cracks the copy protection and puts it on a torrent network, making your sales suddenly drop by 50%.

What scenario you think is more probable? And how can you defend yourself against it? Do think about it...

Me thinks the risks on scenario 1, which truely deals about the IP, is neglectable compared to that of scenario 2. And since the market is open, it takes far more than just a good idea to make it a succes.

We are the KVR collective. Resistance is futile. You will be assimilated.My MusicCalc is back online!!
